[0005] With the rapid development of technology, products that
integrate head-mounted devices with electronic modules have been
developed in recent years for the user to wear the electronic
modules on the head or other parts of the body. For example, a
head-mounted electronic device may be equipped with various
electronic modules (e.g. a display module and a lens module) that
are fixed to a belt body respectively at positions close to the
user's left and right eyes for displaying images to the user's eyes
and recording the view before the user. Some users may prefer using
left eye to watch the images displayed by the display module while
other users may prefer using right eye. To cope with such demand,
head-mounted display devices with two different specifications are
required for disposing the display device on the left and right
sides. However, neither of them is suitable for all the users.
[0006] Since the display module and the lens module are fixed to
the belt body by locking, it is inconvenient for the user to remove
the display module and the lens module or switch their positions.
The installation also takes more time. In addition, after the
positions of the display module and the lens module are switched,
the display module may not be properly aligned with the user's eye
and consequently the user may see lopsided or incomplete
images.
[0007] The information disclosed in this "Description of Related

[0027] Specifically, in this embodiment, the base 130 includes a
base part 131 and a protrusion part 135 that protrudes from the
base part 131. The base part 131 is movably fixed to the belt body
110. Two opposite side surfaces of the protrusion part 135 are
recessed to form two parallel sliding rails 136. As shown in FIG. 2
and FIG. 3, the cover 140 has an "n" shape, and two opposite ends
of the "n" shape extend toward each other to form two sliding
members 142 to be inserted into the two sliding rails 136
respectively, such that the cover 140 is slidably disposed on the
base 130. A length of extension of the sliding member 142 from the
two ends may correspond to a depth of recess of the sliding rail
136, such that the sliding member 142 is engaged with the sliding
rail 136 after being inserted. Nevertheless, in other embodiments,
the base 130 may include the sliding member 142 and the cover 140
may include the sliding rail 136. The positions of the sliding rail
136 and the sliding member 142 are not particularly limited as long
as the base 130 and the cover 140 match each other.
[0028] In addition, as shown in FIG. 4 and FIG. 5, in order to fix
the cover 140 to the base 130, one of the base 130 and the cover
140 includes an arm 137 and a hook 139 that protrudes from the arm
137 while the other includes an engaging indent 144 corresponding
to the hook 139. In this embodiment, the base 130 includes the aim
137 and the hook 139. The arm 137 includes a first end 137a and a
second end 137b that are opposite to each other. As shown in FIG.
4, the first end 137a on the left is connected with the protrusion
part 135 of the base 130 and the second end 137b on the right is
suspended. The second end 137b of the arm 137 includes a plurality
of pressing ridges 138 marking the area to be pressed by the user.
The pressing ridges 138 also increase friction between the user's
finger and the arm 137 and prevent a slip when pressed by the
user's finger. The hook 139 includes a gently sloping surface 139a
facing the first end 137a and a stopper surface 139b facing the
second end 137b. The gently sloping surface 139a and the stopper
surface 139b are connected at an end, and the hook 139 is located
between the first end 137a and the pressing ridges 138 of the
second end 137b. As shown in FIG. 3, a direction that the aim 137
extends from the protrusion part 135 is parallel to an extending
direction of the sliding rail 136.
[0029] As shown in FIG. 3, FIG. 4, and FIG. 5, in this embodiment,
the cover 140 includes an engaging indent 144 that is recessed on a
surface of the "n" shape to face the sliding member 142. The hook
139 is engaged with the engaging indent 144 to fix the cover 140 to
the base 130, such that the electronic module 150 is fixed to the
belt body 110. As shown in FIG. 5, in order to remove the cover 140
from the base 130, the second end 137b of the arm 137 is bent to
disengage the hook 139 from the engaging indent 144 and the cover
140 is pushed to move the sliding members 142 on two ends of the
"n" shape of the cover 140 along the sliding rails 136 of the base
130, so as to be pushed away from the base 130, such that the
electronic module 150 fixed to the cover 140 may be separated from
the belt body 110. Conversely, in order to reinstall the cover 140
to the base 130, the sliding members 142 on two ends of the "n"
shape of the cover 140 are slid into the two sliding rails 136 of
the base 130, and at the same time, the surface of the cover 140
beside the engaging indent 144 pushes the gently sloping surface
139a of the hook 139 of the base 130 to elastically deform the arm
137 until the gently sloping surface 139a passes the surface beside
the engaging indent 144 and the arm 137 elastically recovers for
the hook 139 to engage with the engaging indent 144. Compared with
the stopper surface 139b, the gently sloping surface 139a of the
hook 139 has a smaller angle (not assigned with a reference
numeral) with respect to the surface of the arm 137, by which the
hook 139 is engaged with the engaging indent 144 and confined in
the engaging indent 144.
[0030] Thus, the electronic module 150 may be fixed to the base 130
on the belt body 110 through the cover 140. In addition, the
position of the base 130 on the belt body 110 is adjustable so as
to correspond to the position of the user's eye. FIG. 6 is a
schematic perspective view of the base of the head-mounted display
device in FIG. 1. FIG. 7 is a schematic cross-sectional view of a
part of the belt body and the base of the head-mounted display
device in FIG. 1. Referring to FIG. 6 and FIG. 7, in this
embodiment, the base part 131 of the base 130 includes a through
hole 132, and the belt body 110 is disposed through the through
hole 132 of the base 130. The through hole 132 and the belt body
110 have shapes corresponding to each other. The belt body 110
includes a plurality of protruding ribs 114 on an outer surface
112. In this embodiment, the protruding ribs 114 on the outer
surface 112 of the belt body 110 are aligned at equal intervals.
Nevertheless, the invention is not limited thereto.
[0031] A sliding groove 133 is recessed on an inner surface of the
through hole 132 of the base 130 corresponding to the arrangement
direction of the protruding ribs 114. A bump 134 is disposed on a
bottom surface of the sliding groove 133. When the base 130 slides
with respect to the belt body 110, the protruding ribs 114 move in
the sliding groove 133 of the base part 131. When the base 130
stops sliding, the bump 134 in the sliding groove 133 is limited by
the two adjacent protruding ribs 114 on the belt body 110 and
positioned between the two protruding ribs 114, such that the base
130 is fixed to a certain position on the belt body 110.
Accordingly, the user may adjust the position of the base 130 on
the belt body 110 as desired.
[0032] It should be noted that, in this embodiment, the belt body
110 of the head-mounted display device 100 is a rigid body, which
may be a ring-shaped band or a C-shaped band to be worn on the
user's head. Nevertheless, the disclosure is not intended to limit
the belt body 110 to a certain type. FIG. 8 is a schematic view of
the head-mounted display device according to another embodiment of
the invention. It should be noted that, in FIG. 8, the same or
similar components are assigned with the same or similar reference
numerals and thus details thereof will not be repeated. Referring
to FIG. 8, in this embodiment, a belt body 110a is a soft body.
Therefore, the belt body 110a may be disposed on a helmet 10, and
the user may directly wear the helmet 10 to operate the electronic
module 150. In other embodiments, the belt body may be a
combination of a partially rigid body and a partially soft body.
Nevertheless, the invention is not limited thereto.
[0033] To sum up, the embodiments of the invention achieve at least
one of the following advantages or effects. The base of the
head-mounted display device of the invention is movably fixed to
the belt body. The electronic module is disposed on the cover and
the hook is engaged with the engaging indent to fix the cover to
the base, so as to fix the electronic module to the belt body. To
separate the electronic module from the belt body, the user may
bend the arm to disengage the hook from the engaging indent, so as
to detach the cover from the base. Accordingly, the user may decide
the position of the base on the belt body as desired, and may also
decide whether to dispose the electronic module, which may have
different functions, with the cover to the base near the left side
or the right side. With use of the easy and quick buckle assembly,
the electronic module may be installed to different bases according
to the user's need, which is convenient. Further, the position of
the base with respect to the belt body may be adjusted such that
the bump in the sliding groove on the base is positioned by two
adjacent protruding ribs on the belt body. Thereby, the position of
the corresponding electronic module may be adjusted to improve the
flexibility of use of the head-mounted display device.
